Denial Of Service Attack Case Study

iPremier, a Seattle based company, was founded in 1996 by two students from Swathmore College. iPremier had become one of a few success web-based commerce, selling luxury, rare, and vintage goods over the Internet. Most of iPremier’s goods sell between fifty and a few hundred dollars, and the customer buys the products online with his or her credit card. iPremier’s competitive advantage is their flexible return policies which allows the customer to thoroughly check out the product and make a decision to keep the product or return it. The majority of iPremier customers are high end, and credit limits are not a problem.

LAND DOS attacks: Local Area Network Denial attack is a DoS attack in which a special poison spoofed packet in send to a computer, causing it to lock up itself in a loop.

This type of attack is any event that diminishes or eliminates a network’s capacity to perform its expected function. These attacks are launched against server resources

Denial of service – Denial of service or DOS is an attempt to make a machine or network unavailable to its users. The services that were available to the user wouldn’t be available anymore. Although the result of a DOS attack does not lead to data theft. However a great deal of time and money can cost the company. An example of a service being stopped is email, or can be a loss of network connectivity. There could be no access to shared storage and no one would be able to access the internet while the DOS attack.

The messages sent out on Twitter by Payne on December 2, 2014, contained a link for a Distributed Denial of Service (DDoS) attack on the SLCPA website. The distributed (DDoS) was an attempt to make a machine or network resource inaccessible to its intended users. Networks have a limited amount of connections at any given time. The defendant exploited this limit by initiating as many connections with SLCPA website,

This Denial of Service (DoS) intrusion event started unfolding as the clinic’s users of the internet started to experience such slowness in connecting to systems that they were unable to perform their jobs. This lack of

Describe a situation in which a complete denial of service (DoS) to a user (that is, the user gets no response form the computer) is a serious problem to that user.

This presentation discusses an incident known as a denial of service (DoS) as well as an intrusion of the clinic’s network systems. A denial of service (DoS) attack is designed to shut down services which a business needs to operate. This incident caused widespread slowness and outages to internet services and affected the clinic’s capability to properly treat its patients. In this presentation, the incident is examined. The processes to detect, analyze, contain, eradicate and recover from the

Denial-of-Service attack (DoS) when a hacker continuously attacks a particular network or dedicated Access Point (AP) with fake requests, failure messages and premature successful connection messages and other commands. These causes authorized users from preventing connecting to the network and results in network failure or crash. These attacks depends on misuse of protocols like Extensible Authentication Protocol (EAP).

DNS is critical in the footprinting of a target network. It can sometimes save the attacker a lot of time, or at least corroborate other information that has been gathered. DNS is also a target for several types of attack.

(Conclusion) To conclude, Denial-of-Service (DoS) attacks requires one computer and one internet connection to overload a server’s bandwidth and other resources with TCP/UDP packets.

What are Denial-of-service attacks? According to the Homeland Security's website, it is an attack that prevents the user from accessing information or services, usually by overwhelming the system. "By targeting your computer and its network connection, or the computers and network of the sites you are trying to use, an attacker may be able to prevent you from accessing email, websites, online accounts (banking, etc.), or other services that rely on the affected computer." (McDowell) A distributed denial-of-service attack uses a main host to infect and overwhelm other computers on the same network. Of course, there is no way to completely prevent an attack, but there are ways to reduce the change of getting these attacks. Some good habits are to keep the anti-virus software updated, install a firewall, and to have strong email spam filters. Additionally, regularly keeping backups of important files is always a good idea. If a user falls under this attack, they can contact a DOS Specialist or contact the appropriate Internet Service

Denial of Service (DoS) attack is a very common cyber menace that renders websites and other online means inaccessible to intended users. There are various types of DoS threats and nearly all directly target the core server structure. Others abuse weaknesses in application and communication proprieties. DoS is also used as a cover-up for other wicked actions, and to take down security applications like web firewalls. A prosperous DoS attack is very obvious and impacts the entire online user base.

Denial-of-service is an attack aimed to refuse access for legitimate users and disrupt service availability according to www.msdn.microsoft.com. This type of security threat according to www.tech.co.uk is rapidly increasing on the Internet due to open doors on Websites. By using the Internet, companies increase the risk of denial of service attack. Denial of service can also be caused by too many connected to a server at the same making run slow or unavailable to others. People who deliberately abuse a network server are often difficult to track down.

Distributed denial of service is hard to block. Due to much traffic, system could not tolerate the unacceptable requests from different machines. A single user is attacked from the number of attackers. The millions of requests force the computer to shut down. The main purpose of denial of service is to disturb business of specific organization. The normal work is effected such as make server unavailable to its regular users. A single blockage of an IP address could not stop the attack.
